Installed a 1 1/2" level kit from Rough Country. Now, there is zero rub with 295/70R18 Cooper tires. I pulled up next to a Ford Raptor and felt gigantic. These mods along with a Cold Air Inductions intake and GM Cat back exhaust makes this truck a beast. The final piece, and I agree with everyone who says this mod is absolutely necessary, is the Pulsar LT module that I used to disable DFM, change auto start/stop default to "off", adjust speedometer to tire size and have 5 levels of throttle response at hand at any time. Level "5" will spin the tires if you do more than breathe on the pedal. Fender flares and red caliper covers are the only mods left I have planned at this time.
